Graphene natural rubber old-people shoe sole composite foaming material and preparation method thereof

Abstract

The invention discloses a graphene natural rubber old-people shoe sole composite foaming material and a preparation method thereof. The graphene natural rubber old-people sole composite foaming material is prepared from the following raw materials in parts by weight: 55 to 65 parts of natural rubber, 21 to 28 parts of butyl rubber, 8 to 12 parts of butadiene rubber, 4 to 6 parts of nano medium, 4 to 5 parts of phenylene silanediol, 2.5 to 3.5 parts of hydroxyl-terminated polydimethylsiloxane, 2 to 2.5 parts of graphene, 1.5 to 2 parts of zinc oxide, 2.5 to 3 parts of a stearic acid, 2 to 2.4 parts of zinc stearate, 2 to 2.5 parts of a cross-linking agent, 1.8 to 2.2 parts of a foaming agent and 4 to 5 parts of a lubricating agent. The raw material composition is selected, and the content of each raw material is optimized, so that the prepared graphene natural rubber composite foaming material has a good anti-slip effect; the tensile strength is high, the mechanical property is good, and the durability is good; the density is low, and the ultra-light property is achieved; and the product is especially suitable for a sole material for old people.

Description

[0001] The present invention is a divisional application of an invention patent application with the application number 202010039697.9, the application date is January 15, 2020, and the title is "Graphene Natural Rubber Polymer Sole Composite Foaming Material for the Elderly and Its Preparation Method". technical field [0002] The invention relates to the technical field of polymer composite foaming materials, in particular to a graphene natural rubber composite foaming material for elderly shoe soles and a preparation method thereof. Background technique [0003] Most of the present various soles are made of EVA or rubber materials, the cost is relatively controllable, and properties such as elasticity and hardness can be adjusted according to needs, which has basically met people's requirements. [0004] Natural rubber is the variety with the best coordination of physical and mechanical properties and process performance among rubber materials. It has been widely used in d...

AI Technical Summary

Problems solved by technology

[0007] 1. The anti-skid effect is not good. It is used as the sole material of the elderly, and the elderly are prone to slipping and wrestling;

[0008] 2. After foaming, the tensile strength is greatly reduced, the mechanical properties are poor, and the comprehensive performance is poor; or the degree of foaming is low, and it does not have good portability
